OnePlus 15R Review – 7,400mAh Battery Monster with 165Hz Display

OnePlus 15R Review – A Serious All-Rounder in “R” Clothing

The OnePlus “R” series has always been about giving you near-flagship performance at a more approachable price. With the OnePlus 15R, that idea is being pushed much further. On paper, this phone looks less like a cut-down flagship and more like a very aggressive all-rounder that just happens to sit below the main OnePlus 15. In this OnePlus 15R review based on all the confirmed specs and credible teasers so far, it already feels like one of the most interesting upper mid-premium phones heading to the Indian market this year.

OnePlus 15R Review

Launching in India on December 17 alongside the OnePlus Pad Go 2, the OnePlus 15R is positioned as a rebranded version of the OnePlus Ace 6T from China – but with OxygenOS, India-focused tuning and a pricing strategy aimed directly at performance-hungry users who don’t want to spend flagship money.


Design and Build – Familiar, Functional and Tough

Visually, the OnePlus 15R sticks close to the Ace 6T. The back features a square camera module with two lenses and an LED flash, keeping things clean instead of cluttered. The OnePlus branding sits neatly in the centre, and the frame appears to be metal with a flat-sided look that should feel modern and solid in the hand. Antenna bands cut into the sides, hinting at serious network hardware inside.

The phone is expected to launch in Charcoal Black and Minty Green in India, which matches the more understated, slightly mature design direction OnePlus has taken recently. Power and volume buttons live on the right, with an extra button on the left that could be tied to specific functions depending on the market and software build. At the bottom, the USB Type-C port and speaker grill sit in the usual layout.

What really stands out on the durability front is the certification. The OnePlus 15R is rated IP66, IP68, IP69 and even IP69K, which means dust resistance, water immersion and protection against high-pressure water jets. For a phone in this segment, that level of ruggedness is rare. It positions the 15R as a device you can actually take out in the rain, on treks or to outdoor shoots without constantly worrying about it.

Display – 165Hz at This Price Is No Joke

If you have been following the OnePlus 15, you’ll immediately recognise the panel on the OnePlus 15R. This is a 165Hz 1.5K AMOLED display, expected to be around 6.8 inches with a resolution similar to 1,272 x 2,800, as seen on the Ace 6T. For a phone that will likely sit closer to the upper mid-range segment in pricing, that spec alone is wild.

The high refresh rate, paired with 1.5K resolution, hits a sweet spot between sharpness and efficiency. The display is rated to hit up to 1,800 nits of peak brightness, which should make it more than usable outdoors. At the other end, it can dim all the way down to 1 nit for comfortable viewing at night. TÜV Rheinland Intelligent Eye Care 5.0 certification also hints at better blue-light management and flicker handling, which matters for people who spend hours scrolling, reading or gaming.

There is a hole-punch cutout for the selfie camera at the top, but the surrounding bezels are expected to be slim and fairly symmetrical, based on the Ace 6T design. For a phone that is likely to be priced well below the main OnePlus flagship line, this display might end up being one of its biggest selling points.


Performance – Snapdragon 8 Gen 5 in an “R” Phone

The OnePlus 15R review becomes even more interesting once you look at the chipset. Rather than using a slightly older flagship chip, OnePlus is going straight to Qualcomm’s latest Snapdragon 8 Gen 5, built on a 3nm process. That instantly elevates the 15R from “performance mid-ranger” to “flagship-grade hardware at a lower price”.

OnePlus has also claimed that this Snapdragon 8 Gen 5 implementation was co-developed with Qualcomm over a two-year period, which implies custom tuning on power profiles, thermals and gaming stability. Early Geekbench results hint at strong multi-core numbers, with scores above 9,000 in some tests, and the CPU cluster layout includes two prime cores at 3.80GHz backed by six performance cores at 3.32GHz.

Where this should make a big difference is sustained gaming. The 15R is expected to support high-refresh gaming in titles like BGMI and Call of Duty Mobile at 120 FPS, and with a 165Hz panel, there is room for frame interpolation or future higher-FPS support down the line. Paired with UFS 4.1 storage and at least 12GB of RAM in the base configuration, this phone is positioned to offer serious speed.

On the software side, the OnePlus 15R will ship with OxygenOS 16 based on Android 16 in India. That alone is a big draw for users who prefer the cleaner, more minimal OxygenOS feel over heavy custom skins. It also means better feature parity and long-term update support compared to its Chinese Ace counterpart, which runs ColorOS/HydrogenOS.


Cameras – Focused, Practical Rather Than Over-the-Top

While the main OnePlus 15 aims to be more of an all-out flagship with extensive camera hardware, the OnePlus 15R appears more focused and practical in this area. The rear camera setup is expected to consist of a 50MP primary sensor and an 8MP ultrawide camera, mirroring the Ace 6T.

On paper, that may not sound as flashy as triple or quad-camera setups, but this can actually work in the phone’s favour if OnePlus nails the tuning. The confirmed support for 4K 120fps video recording is a big deal at this price; it was previously reserved for the flagship OnePlus 15. Being able to capture 4K 120fps opens up proper slow-motion workflows for creators who want smoother cinematic motion without dropping to 1080p.

The front camera is expected to be a 16MP unit housed in the punch-hole cutout, which should be adequate for social media, video calls and casual vlogging. If the 15R inherits even a portion of the image processing improvements OnePlus has made on its flagship line, day-to-day performance from this dual-camera setup could be more than enough for most users.


Battery and Charging – 7,400mAh in an “R” Series Body

Battery is where the OnePlus 15R really starts to separate itself from its competitors – and even from the main OnePlus 15 in some ways. The company has confirmed that the 15R will house a 7,400mAh cell, which is the largest battery ever put into a OnePlus phone. That’s 100mAh more than the OnePlus 15 and only slightly smaller than the Ace 6T’s 8,300mAh unit.

The underlying tech is important here. OnePlus is using Silicon Nanostack technology with 15 percent silicon content in the anode, which boosts energy density and helps the battery maintain at least 80 percent of its original capacity even after four years of regular use. For heavy gamers, binge streamers or people who simply do not want to charge their phones twice a day, this is a huge win.

Fast charging on the OnePlus 15R is confirmed at 80W. It’s not quite as extreme as some of the 100W+ solutions on other devices, but paired with such a large battery, it should still deliver a very practical experience – a big top-up in a short time, without overly stressing the cell. If it gets close to the Ace 6T’s behaviour, you can expect a very comfortable single-day or even multi-day battery life for many users.


Price, Variants and Positioning in India

At the time of writing this OnePlus 15R review, the exact Indian price has not been officially revealed. However, there are enough reference points to make an educated guess. In China, the Ace 6T starts at CNY 2,599, which roughly translates to around ₹33,000. Factors like taxes, component costs and OnePlus’ usual India pricing strategy suggest that the OnePlus 15R could land above that – but still noticeably below the full flagship OnePlus 15.

The previous OnePlus 13R launched at ₹42,999 in India, and it would not be surprising to see the OnePlus 15R land somewhere in that band or slightly higher, especially given the Snapdragon 8 Gen 5, IP69-level protection and 7,400mAh battery. The phone will be sold via Amazon India, the OnePlus online store, and likely offline retailers as well, with Charcoal Black and Minty Green confirmed as launch colours.

If OnePlus manages to keep the effective price near the low-₹40K to mid-₹40K segment after launch offers, bank discounts and exchange bonuses, the OnePlus 15R could become one of the most aggressive performance-focused phones in the market.


Early Verdict – Is the OnePlus 15R Worth Waiting For?

Based on everything we know so far, the OnePlus 15R feels like a textbook example of how to do an “R” series phone right. This isn’t just a watered-down flagship; it’s a device with its own identity. A 7,400mAh battery, Snapdragon 8 Gen 5, a 165Hz 1.5K AMOLED display and 4K 120fps video support are headline features you simply don’t expect in a phone that will sit below the main OnePlus 15 in price.

There are still open questions, especially around real-world camera performance, thermal behaviour during extended gaming and the exact Indian pricing. But judging purely by the confirmed specifications and what we know from the OnePlus Ace 6T, the OnePlus 15R is shaping up to be a serious contender for anyone looking for a long-lasting, high-refresh, performance-centric phone that doesn’t cut corners on build quality and durability.

If you are planning an upgrade around the ₹40K–₹50K range and value battery life, display smoothness and raw speed over having three or four rear cameras, the OnePlus 15R is absolutely a phone worth waiting for.

Vivo X300 Pro Review – The Smartphone That Finally Rivals a DSLR

The Vivo X300 Pro is one of those rare devices that immediately tells you what it has been created for. The moment you hold it, the gigantic camera module dominates your visual and physical experience, almost making the rest of the phone feel secondary. Vivo has spent years polishing its camera philosophy, but with the X300 Pro, the company seems to have crossed a line—one where the smartphone is simply the supporting hardware for a professional-grade imaging system. And for anyone who cares about photography, this is a phone that feels almost unreal.

Design & In-Hand Feel

There is no attempt to hide the fact that this device is built around its camera. The bump is huge, the weight is substantial, and the overall footprint immediately reminds you of handling a compact camera rather than a slim flagship. The flat aluminum frame adds a clean, confident look that suits the character of this phone, while the fiberglass back delivers a premium finish that is surprisingly comfortable to hold. Even though it weighs around 230 grams, the balance is surprisingly well managed, and the fit in hand feels reassuring.

The shortcut key on the left side is a welcome addition and quickly becomes a natural part of the way you interact with the phone. It is a thoughtful inclusion, and its customisable action makes the phone feel more personal. The entire structure is protected with IP68 and IP69 ratings, ensuring the durability lives up to the flagship promise.

Display & Multimedia Experience

The 6.78-inch LTPO AMOLED panel continues Vivo’s trend of delivering consistently excellent displays. The reduction in bezel thickness gives the X300 Pro a far more modern aesthetic, opening up the screen and creating an immersive front face that almost disappears in bright environments.

The display is capable of touching 2000 nits in high brightness mode and up to 4500 nits peak, which makes it genuinely usable under harsh outdoor sunlight—something you appreciate instantly when shooting wildlife or portraits outside. The fluidity of LTPO ensures the refresh rate drops and rises subtly based on what you’re viewing, and the combination of HDR, Dolby Vision support and the deep contrast of AMOLED makes media consumption genuinely cinematic.

Performance & Daily Use

The choice of the Dimensity 9500 feels perfect for what this phone aims to be. It is efficient, unusually stable, and powerful enough to handle heavy imaging tasks without thermal discomfort. Benchmarks consistently place it among the top-performing chipsets of the year, but the real magic is how well it holds performance during demanding workloads.

Long 4K shooting sessions, continuous camera use, editing photos, or running games all feel smooth, and the phone rarely heats up in a way that affects performance. The 16GB LPDDR5X RAM and UFS 4.1 storage further elevate the experience, especially when dealing with hundreds or thousands of photos. Even with over 2,000 shots stored, the gallery remains responsive, which says a lot about Vivo’s storage optimization.

Battery Life & Charging

Despite the massive camera housing taking up internal space, Vivo still fits a 6510 mAh battery inside the X300 Pro.

This is impressive on its own, but what stands out is the endurance. Even with heavy camera use, bright outdoor displays, and prolonged 4K recording sessions, the phone comfortably lasts a full day. The included 90W charger brings it up quickly, and 40W wireless charging gives it added convenience. Bypass charging is especially useful for gaming or long shooting sessions where heat management becomes crucial.

Software & User Experience

OriginOS 6 marks a turning point for Vivo’s software identity. It feels cleaner, more refined, and finally flagship-ready. It eliminates many of the complaints people had about past Vivo devices and instead introduces a UI that feels modern, expressive and genuinely helpful.

The animations are fluid, the design language feels intentional, and features like Origin Island, Office Kit and AI-powered utilities add real value rather than simply filling the settings page with clutter. Setting up the ultrasonic fingerprint sensor is also a refreshing experience—you simply rub your thumb instead of tapping repeatedly, and the result is a dramatically faster and more reliable unlock experience.

Camera Performance – The Heart of the Vivo X300 Pro

This is the part of the review where everything else fades away. The Vivo X300 Pro is a masterpiece of smartphone imaging, built around a triple-camera system enhanced by the VS1 and VS3+ imaging chips. These chips handle real-time and post-processing tasks separately, ensuring that while the processor focuses on performance, the imaging pipeline has its own dedicated hardware for detail, dynamic range, colour science and HDR management.

The main 50MP sensor, based on the Sony LYT 828, offers exceptional dynamic range and cleaner tones than its predecessor. The 200MP telephoto lens, however, is the star of the show. Vivo’s optimization adds layers of clarity and stability rarely seen in smartphone zoom systems. Even at high zoom levels, the stabilization remains steady enough to shoot handheld video and still get usable footage—something that simply shouldn’t be possible at 15x, 20x or beyond.

With the optional 2.35x telephoto extender, the experience shifts into a new dimension. Suddenly the phone behaves like a proper telephoto camera, capturing wildlife, birds, action shots and distant subjects with remarkable detail. The extender unlocks focal lengths up to 200mm optically and astonishing levels through hybrid zoom. Some wildlife footage captured with this setup looks indistinguishable from shots taken with a dedicated camera.

x300 pro multi focal hd portraits

Portraits are equally impressive. Vivo has refined its colour science to deliver more natural tones, accurate warmth, and precise detail. The combination of Zeiss portrait modes and the dedicated imaging chips results in images that often look professionally edited straight out of the camera. Night portraits manage to retain texture and warmth without blowing out highlights or drowning shadows. In many ways, this is the first phone that truly feels capable of replacing a DSLR for casual and even semi-professional photography.

Final Verdict

The Vivo X300 Pro starts at ₹1,09,999 for the 16GB/512GB variant, and while the pricing sits at a premium, the experience largely justifies it.

This is not a typical flagship and shouldn’t be compared to one. It is designed for users who want a professional-grade camera system in their pocket, supported by strong performance, long battery life, and the best software Vivo has ever shipped. After days of using it in real-world scenarios, from travel to wildlife photography, the phone consistently delivered results that felt beyond what a smartphone should be capable of.

If you value photography above all else—portraits, wildlife, telephoto, stability, or cinematic video—the Vivo X300 Pro is the best camera phone available today. It is not just an upgrade over the X200 series; it is a complete evolution. And for the first time, a smartphone camera system feels less like a compromise and more like a genuine replacement for traditional cameras.
